Description
Amorphous Silicon (Si) Nanopowder / Nanoparticles for Battery Applications
Purity: 99.99+% | Particle Size: 100 nm | Form: Amorphous | Color: Dark Brown
Amorphous Silicon Nanopowder is a high-purity, non-crystalline form of silicon engineered at the nanoscale. With a particle size of approximately 100 nm and purity exceeding 99.99%, this dark brown powder is ideal for advanced applications in semiconductors, batteries, solar energy systems, and chemical vapor deposition processes.
The powder’s amorphous structure, confirmed via XRD analysis, provides unique electronic properties compared to crystalline silicon. It exhibits enhanced chemical reactivity, isotropic behavior, and improved compatibility with polymer matrices and composite materials. Additionally, the SEM image confirms uniform morphology with excellent dispersibility.
